About 29365: Application of cylinder knee cast
Report 29365 when a clinician applies a cylinder cast that immobilizes the knee while leaving the foot uncovered.
A cylinder cast stabilizes the knee by extending around the leg above and below the joint, while leaving the foot free. Orthopedic clinicians and emergency physicians may apply one for selected knee injuries, including patellar fractures, when the treatment plan calls for cast immobilization rather than a brace or a cast that includes the foot. The service is typically performed in an office, emergency department, or other setting where the cast can be fitted and molded.
Select 29365 for the cylinder configuration, not solely because the knee is being treated. Document the indication, laterality, and cast extent so the record shows that the foot was left uncovered. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. When bilateral casts are reported with modifier 50, CMS pays at 150%. For multiple procedures in one session, the highest-valued procedure is paid in full and other procedures at 50%. Assistant-at-surgery payment is restricted; co-surgeons and team surgery are not permitted.
